How to hide grub2 menu?

Question

I need some help, I screwed up while trying to auto-mount on boot my USB external HDD, something went wrong and it doesn't boot to Ubuntu.

I installed this https://help.ubuntu.com/community/Boot-Repair and I ran it to repair the boot, and now I have a boot menu.

The menu shows down booting and I don't need it so how do I remove it?

Solution

You should use the following steps to hide GRUB (it is still installed)

1. Run this command in terminal

   sudo -H gedit /etc/default/grub
   

2. Set these lines (create them if they don't exist), doesn't have to be this order

   GRUB_TIMEOUT=0
   GRUB_HIDDEN_TIMEOUT=0
   GRUB_HIDDEN_TIMEOUT_QUIET=true
   GRUB_DEFAULT=0
   

3. Save then close the file

4. Run this command in terminal

   sudo update-grub

I think you do need GRUB, it is the program that boots your computer. You could install an alternate bootloader if you needed to, though

tks @minerz029 thing is, i did a fresh install on an empty hdd, and on first boot and the next ones util i screw up grub was never showed. maybe i can disable it ?

GRUB never showed because usually, you press Shift when booting to show GRUB, otherwise it is hidden. Boot repair shows GRUB for you

by "you press shift" you mean that i have deslocated my hand and finger near shift button and pressing it ? It didn't never happen, not on boot.

I think the most helpful resource on this would be the configuration documentation which is not the first thing you'll find when using a search engine: gnu.org/software/grub/manual/html_node/…

Unfortunately this did not work for me. I got the grub menu for 10 seconds.
